Classic Iced Tea

5 tea bags
1 quart water
1-6 Tbsp granulated sugar (depending on desired sweetness)
1 quart ice cubes

Heat tea bags and water in medium nonreactive saucepan over medium heat until dark colored, very steamy, and small bubbles form on bottom and sides of pan (an instant-read thermometer will register about 190 degrees), 10 to 15 minutes. Off heat, steep for 3 minutes (no longer or tea may become bitter). Remove and discard tea bags ; pour tea into pitcher. Stir in sugar, if using, until dissolved; stir in ice until melted. Serve in ice-filled glasses.
